This episode establishes that the Maquis are not Federation citizens. So how come Starfleet is always after them? Okay, some of them have committed crimes in Federation space - Eddington, for example. But many of them have not, yet Starfleet seems to go for any Maquis they can lay their hands on.

Great Moment :

In "Way of the Warrior", Kasidy asks a casual question about all the activity on the docking ring. I was sure that she was Founder infiltrator. The writers pulled a fast one and made her a traitor instead. Nice little touch there.

Plotline

Sisko must face evidence that his girlfriend Kasidy Yates is a trator to the Federation. But she's not the only one...
